The town house that I bought had an instant hot water system..1st quarter $350. 2nd qtr $510. 3 rd qtr 816. YIKES
Bosch 1st qtr which includes 3 weeks with the instant hot water....$206.
Everything I read about this system is true..the only negative thing I can say is that when I rang Bosch c/service for more information, the person i spoke with knew less than I did & wasn't interested in helping.

Bosch Hot Water Heat Pump and it's been mot good due to the controller on the front of the unit it lets me see what the temp in the tank is and it's only db and you can program it to turn on when you want it off like at night its noisey at night. The Bosch Heat Pump poor.

We have had this unit for about 2 years now and not a single problem. We never run out of hot water and we have a family of 4, who take long showers. And our electricity bills have reduced.

My one suggestion would be that Bosch make available some sort of coupling for the exhaust air so that householders can pipe it into the house. My understanding is that the unit works by taking energy out of the air and then returning that air, a few degrees cooler, to the atmosphere. The result is that the unit produces wonderfully cool air! At present the air just cools my garden. It would be great if we could pipe that air into the house (with a shut off valve for winter, of course!). Free air conditioning!

We bought this for a family of 4 and to date nothing but dramas, you have two showers then its no longer hot anymore or it takes so long to heat up again, company was notified and only thing they would do is go around in circles while you suffer. I heard it's compulsory to have when building new dwellings !!! If it is, ... Biggest Scam .

I had an electric system that died so got some advice and THOUGHT that I had made a good decision. A lot of money for a [word removed] system - not a good investment. This system does not get hot. Really bad decision, never buy this system. Bad bad bad, rang Bosch to ask for help and the guy could not give a [word removed] - really great customer service not not not not not.

I changed from a new gas storage system best decision I made. Had it for 3 weeks and already I can see the cost of hot water just going down. I use it on the auto system in conjunction with my solar electric and therefore I have it on only during the day so it cost next to nothing to run. Take a bit of time to understand the various programmes and how they work once you understand them they are very easy.
